Methylenedioxyphenylpropylaminopentane

1-(3,4-Methylenedioxyphenyl)-2-propylaminopentane (MPAP), also known as 3,4-methylenedioxy-α,N-dipropylphenethylamine, N-propyl-1,3-benzodioxolylpentanamine (PDBP), or propyl-K, is a monoaminergic activity enhancer (MAE) of the phenethylamine, amphetamine, and α-propylphenethylamine families that is closely related to phenylpropylaminopentane (PPAP). It is an analogue of PPAP and benzofuranylpropylaminopentane (BPAP) with a benzodioxole ring instead of a phenyl or benzofuran ring, respectively.
